PUZZLE.

SPECIFICATION forming part of Letters Patent No. 474,941, dated May 17,1892. Application filed January 18, 1892. Serial No. 418,395. (Nomodel.)

To all whom it may concern/.-

Be it known that I, ALBERT W. BARTHOLO- MEW, of Boston, in the county ofSufiolk, State of Massachusetts, have invented certain new and usefulImprovements in Puzzles, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invent-ion appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which Figure l as a side elevation of my improvedpuzzle; Fig. 2, a vertical transverse section of the same; Fig. 3, avertical transverse section showing the position of parts after thefirst move for opening the box; Fig. 4, alike view showing the box open,and Fig. 5 a plan view of the locking-disk.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates especially to a box or receptacle locked andunlocked by peculiar movements of the parts constituting the same, andwhich is designed particularly as a toy bank or puzzle; and it consistsin certain novel features hereinafter fully set forth and claimed, theobject being to produce a simpler, cheaper, and more efiective device ofthis character than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation:

In the drawings, A represents the body of the box, which consists of acylindrical block of wood or other material, chambered in one end at bto receive articles. A disk 13, pivoted by a pin cl ecoentrically to thetop of the body, closes the chamber 1). A pivot-pin f passes verticallyand centrally through the bottom of the chamber 17. A locking-disk O, ofthe same diameter as the body, is mounted to rotate freely on the pin f.Said disk is shown in detail in Fig. 5 and is provided centrally with anopening g, through which the pin f passes. A larger circular opening 72.is formed in the disk transsecting the opening j. The bottom of the bodyA has a circular countersink 2', which opens into its pivot-opening andis adapted to register with the opening it in the disk. The disk hasalso an opening of diametrical line with the opening it and disposed onthe opposite side of the pivotopening g. A thicker disk or false bottomD is mounted centrally to rotate on the pivot f below the locking-diskC. The disk D is provided with a countersink or chamber k in the samerelative position as the opening h of the disk 0. A similar chamber m isformed in the disk or bottom D, nearer its periphery than is theopeningj of the disk 0, or nor mally out of line with said opening Thebody A is provided with a vertical hole 10 in the wallof the chamber 1),opposite the coverpivot D. A bolt q is fitted to slide vertically insaid hole, and the coverB is provided with a socket a" near its freeend, adapted to receive the point of said bolt. The head of the bolt qplays freely in a countersink t in the lower face of the bodyAandislocated in such position that the chamber m of the bottom D willregister therewith, as hereinafter described. A ball '1) is disposed inthe countersink t and normally rests on the upper face of thelocking-disk O, the head of the bolt q resting on said ball when thebolt is projected to lock the cover. A ball to is normally disposed inthe countersink t' of the body and opening h of the locking-disk O andrests on the upper face of the bottom D. The parts being in the positionshown in Fig. 2, the cover 13 is locked by the bolt q and the boxpresents the appearance shown in Fig. 1, nothing being exposed but thesmooth surface of the wood other than the heads of the pivots d f.

To unlock the box, the bottomD is rotated until its chamber registerswith the opening h of the locking-disk C, the ball to meanwhile rollingfreely on the bottom D. As said opening and chamber thus register theball to falls into the chamber k, as shown in Fig. 3. The

ball o, meanwhile in the countersink t, has worked on the top of thedisk 0 and is held by said disk supporting the bolt q, as shown in saidfigure. The disk 0 is now pushed laterally between the body A and diskor bottom D, the pivot f entering the opening h of said disk 0. Theopening j of the disk 0 is thus disposed on the same are in which thecountersink i of the body and chamber 'm of the bottom D are rotated. Byholding the disk and bottom in this position and rotating the body untilits countersink t, the chamber m, and the opening j register the ball'1; falls through said openingj into the chamber m,

as shown in Fig. 4:. The bolt q follows said ball '0, leaving the socketr in the cover, when" said cover may be swung laterally'on its pivot,

opening the box.

. To look the box, the cover B is readjusted and the box inverted, so asto throw the point B of the bolt q into the cover-socket '1", when by,slightly rotating the disks 0 D the ball will fall back into thecountersink i, or the position shown in Fig. 2, securely locking saidcover. a I

Having thus explained my invention,what

I I claim is- 1. A puzzle comprising a box, a cover pivoted thereon,abolt concealed in said body and locking said cover, a disk pivoted tothe bottom of said body, a ball disposed in a countersink in said bodyand supporting said bolt, said ball rolling on the inner face of saiddisk, an extension to the pivot-opening of said disk, whereby it may bemoved laterally, and an opening in said disk adapted to register withsaid countersink upon said lateral movement, substantially as described.

2. A puzzle comprising a body, a cover pivoted thereon, a concealed boltnormally locking said cover, a disk pivoted to the bottom of said body,a ball disposed in a chamber formed by an extension of the pivot-openingof said disk and a countersink in said body, a countersink for the headof said bolt in said body, a ball disposed in said countersink andresting on said disk, an opening in the disk on a difierent are fromsaid countersink, a bottom disk mounted on the first disk-pivot, andprovided with a chamber registering with the pivot extensions and with asecond chamber on the same are as the bolt-countersink, all beingarranged to operate substantially as described.

3. A puzzle comprising the body Aand pivoted cover B, the locking-diskO, pivoted on said body and provided with the-openings h j, thecountersinks 1' t in said body, the balls w o, normally disposed in saidcountersinks, the bolt q, normally supported on the ball '0 and lockingsaid cover, the bottom D, fitted to rotate on the pivot of said disk,and provided with the chambers k an, adapted, respectively, to registerwith the openings hy of said disk, all being arranged to operatesubstantially as specified.
